Appliance Won't Turn On 

One of the most routine issues is an appliance that won't switch on. This can be irritating, especially during rush hours. 

Possible Causes: 

• The power cord is unplugged. 

• A blown fuse. 

• Faulty door switch. 

• Overheating. 

How to Fix: 

• First, look whether the product is perfectly plugged in. Sometimes, the cord might have loosened. 

• Check the fuse. If it's damaged, change it and get a new one. Most commercial products have fuses that can be easily replaced. 

• 
  

• Inspect the door switch. Commercial stoves have safety mechanisms that prevent operation when the door is not closed correctly. If the door switch is faulty, you will need to change it. 

• If the offering has overheated, let it cool down for some time. These products have a thermal cutout that shuts down the appliance when it gets too hot.

• Dirt or food particles block the turntable.
